Hellow,
I am currently coding a cocoa/objective-c app. But it seems to be that the class NSNumber does not has methods to calculate the absolute value, sin, cos, tan etc.
Do you have to use another class in the foundation framework or is there somewhere a good 3rd party mathematical framework?
Now I am creating extra methods for NSNumber by creating a categorie for NSNumber. But is there a better solution?
thanks in advance,
Jasper
